If the Ką of a monoprotic weak acid is 3.4 x 10-6, what is the pH of a 0.36 M solution of this acid? pH = Enough of a monoprotic weak acid is dissolved in water to produce a 0.0117 M solution. The pH of the resulting solution is 2.62. Calculate the Ka for the acid. Ka If a buffer solution is...
I attempted to answer some of this question, but don't think I'm understanding what's needed. Chem makes my eyes cross... Liquid ammonia, NH3(l), is an ionizing solvent like water. This means that NH3(l) can dissolve many different ionic compounds and can undergo autoionization. Therefore, there can be acidic, neutral, or basic species in solutions of liquid ammonia. (a) (Write the chemical equation, using the Brønsted-Lowry perspective, that describes the autoionization of NH3(l). --NH3 --> NH2 + H- ?? (b) Identify...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
I added everything thing.
this is the lab question you need to solve.
